Douglas Adams schrieb vor etlichen Jahren:

"... The little dongly things I am concerned with (and they are by no means the only species of little dongly things with which the micro-electronics world is infested) are the external power adaptors which laptops and palmtops and external drives and cassette recorders and telephone answering machines and powered speakers and other incredibly necessary gizmos need to step down the mains AC supply from either 120 volts or 240 volts to 6 volts DC. Or 4.5 volts DC. Or 9 volts DC. Or 12 volts DC. At 500 milliamps. Or 300 milliamps. Or 1200 milliamps. They have positive tips and negative sleeves on their plugs, unless they are the type that has negative tips and positive sleeves. By the time you multiply all these different variables together you end up with a fairly major industry which exists, so far as I can tell, to fill my cupboards with little dongly things none of which I can ever positively identify without playing gizmo pelmanism. The usual method of finding a little dongly thing that actually matches a gizmo I want to use is to go and buy another one, at a price that can physically drive the air from your body.

Now why is this? Well, there's one possible theory, which is that just as Xerox is really in the business of selling toner cartridges, Sony is really in the little dongly power-supply business. ..."
